I did have to expand/minimize the screen a bit to click on buttons...but the forum loading and display issues seem to be resolved with Opera, so it might be good to go with until you locate an option you like better. 
Another option is iCab, but my husband (the computer scientist) told me that iCab has a lot of features and may be a little more clunky with the loading speeds as a result.
